Replace the laser with a single-photon source.
What do expect to measureas we change the path difference?
Conclusion
Exercises
Page 7
1. If only one photon is ever sent into the interferometer, which path does it take afterthe first beamsplitter? Can you relate this to the concept of quantum superposition?
2. Consider an interferometer balanced such that the photon always ends up at D1.Suppose you place a detector, D2, on the bottom path just before the second beam splitter.If you send a single photon through the interferometer, but D3 does not fire,which of D1 or D2 will fire?
3. Discuss how the Mach-Zehnder is related to the double slit experiment.

Gravitational Waves
Gravitational waves are ripples in the fabric of spacetime, stirred up by the changing motions of matter and energy.
The waves are extremely weak by the times they
reach Earth.
GW’s are created by massive moving objects.
Enormous Range of Physics Required to Detect & Understand Gravitational Waves• General Relativity: black holes; gravitational waves;
• Fluid Mechanics & Plasmas: neutron star collisions; supernovae
• Optics: the interferometers
• Statistical physics: noises of all sorts; data analysis
• Elasticity: mirrors; suspensions
• Quantum physics: quantum fluctuations and their control

LIGO is limited by many noises
LIGO is limited by many noises
• Discussion point: A major obstacle in physics research is reducing noise so that you can find a signal.
• How does this apply to the labs we do in our classes?
• Over 20 different sources of noise accounted for
• LIGO detects changes in distance on the scale of 10-18 m.• Equal to change of one atom in the distance between the Earth and Sun.
